Implicit learning of nonlocal musical rules: implicitly learning more than chunks.

Dominant theories of implicit learning assume that implicit learning merely involves the learning of chunks of adjacent elements in a sequence. In the experiments presented here, participants implicitly learned a nonlocal rule, thus suggesting that implicit learning can go beyond the learning of chunks. Participants were exposed to a set of musical tunes that were all generated using a diatonic inversion. In the subsequent test phase, participants either classified test tunes as obeying a rule (direct test) or rated their liking for the tunes (indirect test). Both the direct and indirect tests were sensitive to knowledge of chunks. However, only the indirect test was sensitive to knowledge of the inversion rule. Furthermore, the indirect test was overall significantly more sensitive than the direct test, thus suggesting that knowledge of the inversion rule was below an objective threshold of awareness.

Hierarchical linear modeling of California Verbal Learning Test--Children's Version learning curve characteristics following childhood traumatic head injury.

California Verbal Learning Test-Children's Version (CVLT-C) indices have been shown to be sensitive to the neurocognitive effects of traumatic brain injury (TBI). The effects of TBI on the learning process were examined with a growth curve analysis of CVLT-C raw scores across the 5 learning trials. The sample with history of TBI comprised 86 children, ages 6-16 years, at a mean of 10.0 (SD=19.5) months postinjury; 37.2% had severe injury, 27.9% moderate, and 34.9% mild. The best-fit model for verbal learning was with a quadratic function. Greater TBI severity was associated with lower rate of acquisition and more gradual deceleration in the rate of acquisition. Intelligence test index scores, previously shown to be sensitive to severity of TBI, were positively correlated with rate of acquisition. Results provide evidence that the CVLT-C learning slope is not a simple linear function and further support for specific effects of TBI on verbal learning.

Word learning in a supported-learning context by preschool children with specific language impairment.

Word learning in a supported-learning context is described for 30 preschoolers with SLI and 30 age- and sex-matched children without SLI. Daily production probes assessed number of words learned to criterion, and daily posttests assessed comprehension of the words. Number of words produced to criterion differed between groups; however, the majority of children with SLI performed within the range of the children without SLI. Children typically comprehended words they did not produce to criterion. The relation between vocabulary-test and word-learning findings was not significant (p < .05). Findings for children with SLI indicate that (a) comprehension does not ensure same-word production, (b) word-learning potential cannot be inferred from test scores, and (c) a clinically significant variability in word-learning skills characterizes the disorder.

Nursing students' response to self-directed learning: an evaluation of a learning process applying Jarvis' framework.

This paper evaluates the effectiveness of a student-centred module of learning using Jarvis' experiential framework. One hundred and thirty-five students undertook the module over a 9-month period. A semi-structured questionnaire was used to explore students' learning, choice of topic, structure, and benefit of the module. The data were analysed using simple descriptive statistics and content analysis. A key theme emerged related to the beneficial learning experience. Presentation skills/shared learning, choice and autonomy, taking responsibility, and research skills were other themes that emerged. Whilst the literature suggests students dislike experiential forms of learning, the positive evaluation of this module demonstrates that it can be used effectively. Furthermore, Jarvis' model provides a useful framework for structuring this approach to learning. One of the research strategies within a nursing faculty should be to develop progressive student-focused educational methods and evaluate their effect or professional preparation. This, it is argued, needs to be perceived as a valuable and essential activity within an academic nursing department.

Implicit learning in memory rehabilitation: a meta-analysis on errorless learning and vanishing cues methods.

The objective of this study was to present a quantitative review on the treatment effects of memory rehabilitation techniques based on intact implicit learning capacity in amnesic patients, that is, errorless learning and the method of vanishing cues. English-language journal articles focusing on these rehabilitation techniques were examined using MedLine (1966-2002) or PsychInfo (1887-2002), as well as additional papers listed in the references of these articles. Studies had to meet the following inclusion criteria: (1) original data were reported, (2) memory rehabilitation was studied in memory-impaired patients, (3) a control intervention was included, (4) exact scores were listed for both intervention conditions, or the exact statistics were presented. Studies were classified on the basis of the to-be-learned material and the method of intervention (errorless learning, vanishing cues, control intervention), patient characteristics were determined, and the tasks that were used were taken into account. Effect sizes and variances were computed for each individual study compared to control treatment using within-group statistics. A "large" and statistically significant ES was found for errorless learning treatment, but no significant ES was demonstrated for the vanishing cues method. The results of the present study show that the errorless learning technique is effective in amnesic patients. The effects on the vanishing cues method are only small (and nonsignificant).

Cooperative learning and peer acceptance of students with learning disabilities.

The effects of cooperative learning on 417 regular-education students, acceptance of 41 of their special-education classmates were examined in an 8-month study. The participants were in Grades 5-8 in 21 classes in 2 U.S. schools. The 3 conditions were cooperative learning and competitive learning, taught by the same teachers, and competitive learning, taught by a random sample of teachers. In October and in May, the regular-education students rated each classmate's desirability as a work partner. The students' peer ratings were generally very stable, for both their regular-education classmates and their special-education classmates. Positive changes in peer ratings for both types of classmates occurred more frequently in the cooperative-learning condition than in the competitive-learning conditions.

Learned irrelevance and retrospective correlation learning.

In 1973 Mackintosh reported an interference effect that he called learned irrelevance in which exposure to uncorrelated (CS/US) presentation of the unconditional stimulus (US) and the conditioned stimulus (CS) interfered with future Pavlovian conditioning. It has been argued that there is no specific interference effect in learned irrelevance; rather the interference is the sum of independent CS and US exposure effects (CS + US). We review previous research on this question and report two new experiments. We conclude that learned irrelevance is a consequence of a contingency learning and a specific learned irrelevance mechanism. Moreover even the independent exposure controls, used in previous experiments to support the CS and US exposure account, provide support for the correlation learning process.

Variational learning and bits-back coding: an information-theoretic view to Bayesian learning.

The bits-back coding first introduced by Wallace in 1990 and later by Hinton and van Camp in 1993 provides an interesting link between Bayesian learning and information-theoretic minimum-description-length (MDL) learning approaches. The bits-back coding allows interpreting the cost function used in the variational Bayesian method called ensemble learning as a code length in addition to the Bayesian view of misfit of the posterior approximation and a lower bound of model evidence. Combining these two viewpoints provides interesting insights to the learning process and the functions of different parts of the model. In this paper, the problem of variational Bayesian learning of hierarchical latent variable models is used to demonstrate the benefits of the two views. The code-length interpretation provides new views to many parts of the problem such as model comparison and pruning and helps explain many phenomena occurring in learning.

Introducing the Learning Practice--I. The characteristics of Learning Organizations in Primary Care.

RATIONALE, AIMS AND OBJECTIVES: This paper is the first of three related papers exploring the ways in which the principles of Learning Organizations (LOs) could be applied in Primary Care settings at the point of service delivery. Here we introduce the notion of the Learning Practice (LP) and outline the characteristics and nature of an LP, exploring cultural and structural factors in detail. METHODS: Drawing upon both theoretical concepts and empirical research into LOs in health care settings, the format, focus and feasibility of an LP is explored. RESULTS AND CONCLUSIONS: Characteristics of LPs include flatter team-based structures that prioritize learning and empowered change, involve staff and are open to suggestions and innovation. Potential benefits include: timely changes in service provision that are realistic, acceptable, sustainable, and owned at practitioner level; smoother interprofessional working; and fast flowing informal communication backed up by records of key decisions to facilitate permanent learning. Critical comment on potential pitfalls and practical difficulties highlights features of the present system that hinder development: tightly defined roles; political behaviours and individual-oriented support systems; plus the ongoing difficulties involved in tolerating errors (whilst people learn). This paper contributes to the wider quality improvement debate in the area in three main ways. First, by locating Government's desires to create health systems capable of learning within the theoretical and empirical evidence on LOs. Second, it suggests what an LP could be like and how its culture and structures might benefit both staff and patients in addition to meeting externally driven reforms and health priorities. Third, it extends the application of LO concepts to the health care sector locating the principles in bottom-up change.

Student perceptions of a virtual learning environment for a problem-based learning undergraduate medical curriculum.

OBJECTIVE: To investigate the effects of a virtual learning environment (VLE) on group interaction and consultation of information resources during the preliminary phase, self-study phase and reporting phase of the problem-based learning process in an undergraduate medical curriculum. METHODS: A questionnaire was administered to 355 medical students in Years 1 and 2 to ask them about the perceived usefulness of a virtual learning environment that was created with Blackboard for group interaction and the use of learning resources. RESULTS: The students indicated that the VLE supported face-to-face interaction in the preliminary discussion and in the reporting phase but did not stimulate computer-mediated distance interaction during the self-study phase. They perceived that the use of multimedia in case presentations led to a better quality of group discussion than if case presentations were exclusively text-based. They also indicated that the information resources that were hyperlinked in the VLE stimulated the consultation of these resources during self-study, but not during the reporting phase. CONCLUSIONS: Students indicated that the use of a VLE in the tutorial room and the inclusion of multimedia in case presentations supported processes of active learning in the tutorial groups. However, if we want to exploit the full potential of asynchronous computer-mediated communication to initiate in-depth discussion during the self-study phase, its application will have to be selective and deliberate. Students indicated that the links in the VLE to selected information in library repositories supported their learning.

Roles for learning sciences and learning technologies in biomedical engineering education: a review of recent advances.

Education in biomedical engineering offers a number of challenges to all constituents of the educational process-faculty, students, and employers of graduates. Although biomedical engineering educational systems have been under development for 40 years, interest in and the pace of development of these programs has accelerated in recent years. New advances in the learning sciences have provided a framework for the reexamination of instructional paradigms in biomedical engineering. This work shows that learning environments should be learner centered, knowledge centered, assessment centered, and community centered. In addition, learning technologies offer the potential to achieve this environment with efficiency. Biomedical engineering educators are in a position to design and implement new learning systems that can take advantage of advances in learning science, learning technology, and reform in engineering education.

The effects of learning strategy instruction on the completion of job applications by students with learning disabilities.

The purpose of this study was to assess the effects of learning strategy instruction on the completion of job applications by students identified as learning disabled. Thirty-three students (average age 15 years 6 months) were randomly assigned by grade and gender to one of two experimental conditions: learning strategy instruction or traditional instruction. The result was 16 students (10 boys and 6 girls) being placed under the learning strategy instruction condition and 17 students (10 boys and 7 girls) being placed under the traditional instruction condition. Results indicated that in addition to statistically significant lower numbers of information omissions and information location errors, holistic ratings of the overall neatness of the job applications were significantly higher for those students under the learning strategy instruction condition. In addition to these positive changes in the performance measures, social validity data suggest that students under the learning strategy condition would be more likely to receive an invitation for a job interview. The findings and future research needs are discussed.

Brain correlates of language learning: the neuronal dissociation of rule-based versus similarity-based learning.

Language learning is one of the mysteries of human cognition. One of the crucial questions is the following: Does acquisition of grammatical knowledge depend primarily on abstract rules or on item-specific information? Although there is evidence that both mechanisms contribute to language acquisition, their relative importance during the process of language learning is unknown. Using an artificial grammar paradigm, we show by means of functional magnetic resonance imaging that the brain dissociates the two mechanisms: the left anterior hippocampus supports similarity-based learning, whereas the left ventral premotor cortex is selectively engaged by abstract rule processing. Moreover, data analysis over time on learning suggests that similarity-based learning plays a nonobligatory role during the initial phase, and that rule-based abstraction plays a crucial role during later learning.

Decomposing serial learning: what is missing from the learning curve?

Our current understanding of serial learning relies on the form of the learning curve and on changes in the serial position curve over repeated study-test trials (Ward, 1937). The averaging of data that produces these functions obscures the detailed history of memory for individual items over the course of study-test trials. Extending Tulving's (1964) analysis of free recall learning, we present a new analysis of serial learning that tracks the acquisition and forgetting of item and order information at the level of individual items. Applying this analysis to two large data sets on serial list learning allows us to discern among hypotheses that are indistinguishable solely on the basis of the learning curve.

Domains of learning: interdependent components of achievable learning outcomes.

"Domains of learning" refers to the three separate, yet interdependent components of learning outcomes achievable by human learners. These domains--cognitive, affective, and psychomotor-represent various categories and levels of learning complexity and are commonly referred to as educational taxonomies. The cognitive domain refers to knowledge attainment and mental/intellectual processes. The affective domain characterizes the emotional arena reflected by learners' beliefs, values and interests. The psychomotor domain reflects learning behavior achieved through neuromuscular motor activities. Educators use the domains to assist in determination of learning objectives essential to planning, implementing and evaluating teaching-learning processes and outcomes of human learners across the life span. Actual instances of domain use from programs, interviews and the literature complement the theoretical notions presented in this article.

Design of a CSCL environment for clinical reasoning learning and problem-based learning in medicine.

The medical curriculum is changing, student-centered learning is currently used in medical schools. Problem-based Learning and Clinical Reasoning Learning develop the students' reasoning strategies. CSCW (Computer-Supported Cooperative Work) technology is used in Problem-Based Learning systems. We have designed a CSCL (Computer-Supported Collaborative Learning) environment for improving group coordination and communication in Clinical Reasoning Learning sessions. To support these new educative technologies, a prototype has been developed.

Students can learn medicine with computers. Evaluation of an interactive computer learning package in geriatric medicine.

OBJECTIVE: To assess the effectiveness of a computer-aided learning program on dementia. DESIGN: Fourth year medical students were arbitrarily assigned to groups that used a computer-aided learning program (65) or had a tutorial covering similar material (73). These sessions were in addition to a base curriculum in a two-week course in geriatric medicine. MAIN OUTCOME MEASURES: The effectiveness of the teaching sessions was judged by the performance on a multiple choice questionnaire about dementia, given to the students on two occasions, one at the beginning and one at the end of the two-week course. RESULTS: Both groups of students scored significantly better on the second test (computer group, 66% [95% confidence interval, 64-69] to 81% [79-83] and tutorial group, 66% [63-67] to 74% [73-77]). The difference between the groups at the start of the course was not significant (F1,136 = 0.61, P = 0.61); however, there was a significant difference between the groups at the end of the course (F1,136 = 21.83, P < 0.001). CONCLUSION: Both groups improved their knowledge of dementia during the two-week course. Students who used the computer-aided learning programs showed a greater improvement in score. Computer learning programs are effective learning tools and are a useful addition to traditional teaching methods. Further study is required to assess the effects of computer-aided learning programs in long-term studies of dementia knowledge.

Cognitive and learning profiles of delinquent and learning-disabled adolescents.

The association between juvenile delinquency and learning disabilities has been a focus of considerable discussion and controversy. Nevertheless, only a limited number of investigators have directly contrasted these two populations. In those studies which have examined the link between antisocial behavior and school problems, research methodology has varied, resulting in conflicting evidence and limited consensus. The present study was designed to address this issue by comparing the cognitive and learning profiles of delinquents and learning-disabled adolescents. Specifically, 53 delinquents, 26 learning-disabled adolescents, and 50 average achievers were evaluated with newly developed educational and cognitive inventories. These assessment techniques were used to analyze several functional areas including processing efficiency, problem solving, and response style. Application of discriminant analysis to the cognitive and educational profiles of these adolescents suggested the existence of various subtypes of delinquency. Learning disabilities characterized one of these subgroups. It was concluded that more specific descriptions of the learning profiles of adolescent delinquents holds promise for rehabilitation and, perhaps, prevention of juvenile delinquency.
